In the reflecting mirror of the present invention, the film thickness of a photocatalytic hydrophilic film mainly made of silicon dioxide is set to about 90 nm, and the mass ratio of photocatalyst particles made of titanium dioxide contained in the photocatalytic hydrophilic film is set to about 60%. As a result, the hydrophilicity and the photocatalytic property can be sufficiently assured, and the surface reflectivity of the photocatalytic hydrophilic film can be effectively restrained. Therefore, the occurrence of a double image caused by the surface reflection of the photocatalytic hydrophilic film can be effectively restrained or be prevented.
